and development of a balanced absorption of nutrients Evodia. (B) Analysis of Evodia forest soil chemical properties (1) Different Fertilizer Evodia forest soil ammonium N, available phosphorus and potassium content of the changes Nitrogen, phosphorus and potassium act as necessary for plant growth as a large number of elements in plants throughout the growth cycle, plays an important Evodia balanced fertilization in the cultivation of the research, soil ammonium nitrogen, available phosphorus, available potassium as Evodia forest soil chemical properties analysis of important indexes, in the experiments their content were analyzed for fertilizer before and after to statistics, statistical results in Table 3 Table 3: Different Fertilizer Evodia forest soil ammonium N, available phosphorus and potassium content of the changes 单位： (mg/L) 类别Categories N1P1K0 N1P1K1 N1P1K2 N1P2K1 N1P2K2 N1P0K1 CK 总体Total 铵态氮Ammonium 速效磷Available phosphorus 速效钾Potassium This table methodology: a testing ground for various regions, the same treatment before fertilization, after fertilization of soil nutrient content of the difference， Units： mg/ L。 From Table 3:In all fertilization treatments, the soil samples Evodia ammonium nitrogen and available phosphorus content of changes are higher than CK. processing. From the various processing soil fertilizer increased situation, the largest increase in focus on N1P1K1 processing, the value of mg / L. N1P1K0 and N1P0K1 of fertilizer increased values are mg / L and mg / L. The use of soil ammonium nitrogen is not very high. Therefore, the bined application of NPK fertilizer on soil ammonium content increased effect of the best, singletreatment of P fertilizer or potash fertilizer improve soil ammonium concent effect is not obvious . From the various processing the use of Available phosphorus, N1P2K1, and N1P2K2 deal with changes of soil available phosphorus content are higher than other treatments, CK processing is negative, the relative decrease mg / L before fertilization, To illustrate that the reasonable application can improve pertinence of anic p utilization. From the various processing rapidlyavailable potassium using, N1P1K0 processing in the content of soil rapidlyavailable potassium to reduce performance in change, for / L, Among the N1P2K1, N1P1K2 and N1P2K2 processing changes, soil available K content is higher, and N1P2K1 is the highest to / L,. It showed a reasonable application of NPK which is conducive to the accumulation of potassium, rather than application of potash fertilizer, the soil will soon be in a potential depletion of potassium in the state. Thus, in Fertilization NPK fertilizer to improve soil nutrient content on the most obvious effect of a single P fertilizer or potash can not effectively improve soil nutrient content, and even lead to lack of soil nutrients. (2) Different fertilizer formulas Evodia forest soil anic matter content and the changes in PH value Soil anic matter is from the tuyuhun life of the soil, including soil microbes and soil animals and their secretions, as well as plant residues in soil and plant secretions. Soil anic matter is one of the key indicators of high and low soil fertility, due to regional climatic conditions, vegetation types and tillage management is different from the plants into the soil residues of the volume and chemical position are very different, which is the main source of soil nutrients , and can improve soil physical properties, which have the biological activity and plexation, helping to eliminate the pollution of the soil and promote growth of trees and improving the ability of soil protection and buffer properties of fat plays an important role. Soil pH and say soil reaction. It is the soil solution of the acidbase reaction. In soil solution depends on the concentration of hydrogen ions, pH value. The effectiveness of soil pH on nutrient a great impact in agricultural production should pay attention to soil pH, and actively take measures to adjust. Table 4: Different Fertilizer Evodia forest soil anic matter content and the changes in PH value 处理Categories 有机质 含量 Organic matter content（％） PH 值 PH Value 施肥前Prefertilization 施肥后After fertilization 变化Change 施肥前 施肥后 变化 N1P1K0 N1P1K1 N1P1K2 N1P2K1 N1P2K2 N1P0K1 Ck 总体 Total From Table 4: Evodia sample content of soil anic matter content in after fertilization, the overall trend is not very large, increased %. Sample each processing in the fertilization of soil anic matter content increased degree relatively CK. Changes of soil anic matter content of each processing is relatively clear that the biggest changes is N1P1K1, to %, N1P1K0 and N1P0K1 variation is small relatively, % and % respectively. Description of balanced fertilization for soil fertility, increasing soil anic matter content have a very good role in promoting the same time, soil fertility, anic matter can be well reflect the soil fertility and characterization of soil fertility.. PH value changes is the most N1P1K1,for , and is the lowest N1P1K0,for , followed N1P0K1,for Fertilization pH value changes of each treatment are greater than CK processing. Description NPK balanced fertilizer can improve effectively the soil pH, because the nitrogen and potash fertilizer applie into the promotion of Evodia absorption and utilization of phosphate fertilizer, reducing the accumulation of phosphate in the soil and eventually result in the increase of soil pH values. The increase of pH value make for microbial activity, and increased the soil available nutrient content, which is very beneficial for the growth of trees.。
